Smith, the 44-year-old actor whose 14-year-old son Jaden has been public about his friendship with 19-year-old Bieber, recently defended the Canadian pop star amid negative media reports.

"We think it hugely important to support young artists, there is a war against that kind of artistry, that kind of creation," Smith told Extra correspondent Angie Martinez at the premiere of "Free Angela And All Political Prisoners." "When somebody is 19 years old, they're gonna do what they're gonna do just like we did."

Bieber has made media headlines for his social media rants, parties, aggression and performing his recent shows later than scheduled. Although Bieber has also defended his recent actions in the media, Smith said he has made it clear that his son's friend can always look to him for support.

"For me the most important thing was for him to know anytime he can call and I'll come whatever happens," Smith said at the recent movie premiere. "At that age that's what you need to know you can do what ya gonna do, but you have somewhere you can go, where you can find safety."

"Is it okay to continually attack and criticize a famous 19 year old who is simply trying to build a life, exercise his talents while figuring out what manhood and fame is all about as he carries the weight of supporting his family as well as providing the paychecks to others who depend on him to work so they can feed their families as well," Pinkett-Smith questioned on Facebook. "Does that render being called a (expletive) by an adult male photographer as you try to return to your hotel after leaving the hospital?"

Bieber took to his personal Twitter account to thank Smith's husband Will for encouraging him during tough times.

"Love to big man Will Smith for the great talk yesterday," Bieber tweeted earlier this month. "We know the truth and we must stand tall. Love u man! thanks!"
